Antidepressants for Hot Flashes
How It Works
Selective serotonin reuptake inhibitors (SSRIs) affect the brain's use of a neurotransmitter chemical called serotonin, which is thought to have a role in regulating body heat. Increased serotonin use by the brain can also improve perimenopausal mood swings and irritability.
Venlafaxine affects the brain's serotonin and norepinephrine levels. How it affects hot flashes is not known. Mood may also improve with venlafaxine use.
Why It Is Used
Select antidepressants are used to treat hot flashes affecting menopausal women. They may also help with irritability, depression, and moodiness. They can be used before and after menopause as a symptom treatment alternative to hormones (birth control pills or hormone therapy [HT]).

The U.S. Food and Drug Administration (FDA) has issued an advisory on antidepressant medicines and the risk of suicide. The FDA does not recommend that people stop using these medicines.

What To Think About
Never suddenly stop taking antidepressants. The use of any antidepressant should be tapered off slowly and only under the supervision of a doctor. Abruptly stopping antidepressant medicines can cause negative side effects or a relapse of your condition.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
